全现浇剪力墙结构钢筋安装(国外英文资料) The construction of the steel bar is installed First, the working conditions According to the specification of the design drawing, choose the appropriate feed length to avoid waste, and the rebar processing or welding net. The rust on the surface of the steel bar is cleaned before the binding. The dimensions, specifications and quality of the meshing of the meshing are available. Play the wall and the line of the hole, and remove the loose concrete from the seams. The electroslag pressure welder should be trained by the internal training and shall be tested and qualified before the class. Prefabricate the cement mortar block or purchase plastic card as protective layer. Familiar with drawing and technical background. Two, material requirement The steel bar has the factory quality certificate and is qualified by the examination. Third, construction equipment The bar hooks, crowbars, nets, bands, steel wire brushes, steel bars, stone pens, ink fights, rulers, etc. Second, process flow The line and the pretest, the forming bar approach, the bar, the welding joint, the binding and the post of the wall, and the acceptance of the transfer Third, operation craft The repair is reserved for stretching According to the wall line, adjust the extension of the lower wall to make the position correct. If the wall of the lower floor is outstretched, the design staff should be consulted. Generally press 1:6 adjust, with steel mesh piece to catch up. Second, the welding, the lashing of the joints For the dark columns, doors and Windows at the hole edge artifacts such as the vertical force appropriate reinforcement mechanical connection or welding, to three or four seismic grade, when D 22 mm or less, can use the welded lap joints. It is easy to think about economy and operation, and use electroslag pressure welding. The anchorage length of reinforcing bars around the hole should meet the requirements of construction detail of earthquake seismic construction (03
